Answer first
An Instagram transcript records spoken words, usually with optional timestamps. Subtitles synchronize dialogue for viewers who may not understand the spoken language. Captions synchronize dialogue and can also describe relevant sound effects or speaker changes for viewers who cannot rely on audio.
Quick comparison
- Transcript: best for search, notes, research, and editing. It may be plain text or timestamped.
- Subtitles: timed dialogue, often translated or adapted for another language.
- Captions: timed dialogue plus useful audio context, such as [music] or a speaker label.
Which file should you export?
Use TXT when you only need searchable notes. Use SRT for broad editor compatibility and VTT for web video players. Both SRT and VTT carry cue timing, but neither guarantees that line breaks, reading speed, or sound descriptions are ready for publication.
One transcript can support all three
- Create a timestamped speech transcript from an authorized local file.
- Correct names, numbers, and uncertain words against the original.
- Adapt the wording for subtitles if a translation is needed.
- Add sound descriptions and speaker labels for an accessible caption track.
- Preview the result with the video before publishing.
The common mistake
Do not treat a transcript as finished captions just because every spoken word is present. Captions need timing, readable segmentation, and enough context for someone who cannot hear the audio.
